Do Humans Have a Future Beyond Earth?

“I think it’s a dangerous delusion to envisage mass emigration from Earth. There’s nowhere else in the solar system that’s as comfortable as even the top of Everest or the South Pole. We must address the world’s problems here. Nevertheless, I’d guess that by the next century, there will be groups of privately funded adventurers living on Mars and thereafter perhaps elsewhere in the solar system. We should surely wish these pioneer settlers good luck in using all the cyborg techniques and biotech to adapt to alien environments. Within a few centuries they will have become a new species: the post-human era will have begun. Travel beyond the solar system is an enterprise for posthumans—organic or inorganic.”
